NEW YORK (CNNMoney.com) -- Stocks turned mixed Tuesday morning after falling in the early going, as investors considered a range of quarterly results but also opted to dip back in after the previous session's retreat.

The Dow Jones industrial average (INDU) lost 27 points, or 0.3% around 30 minutes into the session. The S&P 500 (SPX) index fell 2 points, or 0.2%. The Nasdaq composite (COMP) gained 9 points, or 0.5%.

A six-week old rally for U.S. stocks lost ground Monday. Wall Street sank on worries about financial sector profits after Bank of America (BAC, Fortune 500) posted better-than-expected results but warned of "deteriorating credit quality."
